APPLE PARER, CORER, AND SLICER.

SPECIFICATION forming part of Letters Patent No. 273,418, dated March 6,1883, Application filed May 17, 1882. (No model.)

T all whom it may concern Be it known that I, DAVID H. WHITTEMORE,

. of Worcester, in the county of Worcester and State of Massachusetts,have invented certain new and useful Improvements in Apple-Parers, ofwhich the following is a specification.

My invention relates toimprovements in apple-parers in which alongitudinally-moving screw-shaft is employed in connection with apeculiar stop knock-off, slicing-knife, and frame, all as hereinafterdescribed.

Said improvements are illustrated in the accompanying drawings, in whichFigure l 'isa front view of my apple-pater. Fig. 2 is a side view of theslicing and coring knife. Figs. 3 and 4 are rear views of detachedparts, illustrating the operation of the knock-oft; and Fig. 5 isa sideview of detached parts, together with a transverse section of thescrew-shaft.

A designates a screw-shaft having both a longitudinal and rotarymovement. At one of its ends the operating-crank a is secured, and atthe opposite end is the fork b, by which the apple is held while beingpared. This shaft A has its bearings and support in-the middle portion,0, of the frame B, and is fitted to slide longitudinally through thebearings in which it revolves. A swinging latch, d, is hung to saidmiddle portion, and engages 'the screw or spiral groove 6 of the shaftA. The

upper end of this latch is well curved, so as to reach around and extendover the top of the shaft A to apoint somewhat in the rear of the axisof the latch, so that the forward rotary motion of the shaft will have atendency to hold said latch into engagement with the screwshaft withoutthe aid of a spring. If desired, however, a spring,f, may be added, asshown in Figs. 1, 3, and 4, to assist in holding the latch inengagement; but it is believed that the latch is practically operative,either with or without the spring. The thread or groove 0 of thescrew-shaft runs'into the stop-groove av, Fig. 1, which extends directlyaround the shaft. By turning the crank forward when the latch is in thegroove e, the shaft A moves longitudinally forward until the latch runsinto the groove .90.

Upon the end of the shaft which bears the fork b is the knock-0E g,arranged to slide longitudinally back and forth on said shaft from theposition shown in Fig. '3 to that shown in Fig. 4, and return. Theknock-oft is composed of a solid end, which surrounds the fork-shaft,andthree arms which extend lengthwise with the forkshaft over the headof the fork, where said arms are provided with inwardly-projecting lugs,which lie between the fork-tines. In putting the parts together thethree arms are spread open, or left open when cast, and after slippingthem over the forkhead they are bent inward into the position shown inthe drawings. This construction is quite simple and inexpensive. Theknock-off is limited in its movements by the solid end which surroundsthe shaft, and the inner' lugs (indicated by broken lines) at theopposite end of the knock-off, and the head of the fork. When an appleis placed upon the fork, the knock-off is forced by the apple toward thecrank end of the shaft, as shown in Fig. 3. After the apple is pared thelatch d is held back out of engagement with the shaft A, therebybringing the knock-off stop It up into the path of the knock-off. Theshaft, with the fork and core thereon, is drawn back when the knock-oftg is stopped by the knock-off stop h. The further backward movement ofthe shaft draws the fork into the knock-off, as shown in Fig. 4, andclears the fork of the core or apple.

From the middle portion, 0, of the frame B there extends downward belowthe screw-shaft another part for a clam ping-frame, i, provided withclamp-screw j, by means of which to secure the device in place for use.Another part of the frame B extends upward from the middle part, andthen horizontally to the left, thereby forming the bar 70, and to thisbar It the paring knife I, slicing and coring knife G, and breaker n aresecured. The three parts of the frame are rigidly connected in the oneframe B, as by casting all in one piece, or in any proper manner. Theparing-knife is of ordinary construction, and is hung so as to 5 swivel,and' also to swing outward, but is secured against moving longitudinallyon the bar 70 of the frame B. The breaker 0 is older than the inventionintended to be protected by this patent. The slicer and coring knife [00G is in scroll form, as shown most clearly in Fig. 2, with a wing, q,bent out from the inside of the coil at the small end of the scroll,having one edge sharpened to form a coreknife, while a short flange, s,is, also turned out from said coil to form a core-guard. Thisscroll-shaped knife is bent flatwise, to give it a spiral or helicalpitch, as in various other slicer-knives. The inner edge from the cornerto to the core-knife or wing q is sharpened; and it should be noticedthat not only is the general form of the complete knife in scroll form,but this cutting-edge is substantially in scroll form, beginning at thepoint-u, and extending partially around the axis of the fork to thecore-knife q upon the opposite side of the axis from the starting-pointu. The scroll form of this cutting-edge gives a good drawing cut for itswhole length, and the construction of the knife is very simple. It isevident that all the advantages of this form of cuttingedge for theslicer-knife will be present whether or not the core-knife andcore-guard are formed in tegral'therewith or of a separate piece orpieces. In fact, for some uses I prefer to form the core-guard of castmetal upon a thin plate placed by the side of the slicing-knife. I havedescribed the slicer and coring-knife as in scroll form because ofitsgeneral appearance as viewed in side view; but it should be noticed thatthe flange s, which forms the core-guard, is on the are of a circle. Theconstruction of the frame is such. that the knives are freed veryreadily, and neither the parin gs nor sliced apple will fall upon anypart of the frame. The knock-off is one that is very convenient and easyto operate.

I claim as my invention- 1. The slicing-knife having its cutting-edge inscroll form extending partially around the fork-axis to a point oppositethe starting-point of said edge, substantially as described, and for thepurpose specified.

2. The apple-parer consisting of the slicing and paring knives dependingfrom the horizontal bar k, which forms the upper part of the frame B,and secured thereon against moving longitudinally, the screw-threadedforkshaft arranged parallel to said bar to move longitudinally throughthe bearings in which it revolves in the middle part, c, of the frame,and the clamping-frame i, forming the lower part of the frame B,and-standing under the crank end only of the bar is at a point below thefork-shaft, all substantially as described, and for the purposespecified.

3. The knockoff consisting of the solid end for surrounding thefork-shaft and the three arms which extend over the head of the fork andterminate with the inwardly-projecting lugs, substantially as described,and for the purpose specified.

4. The combination of the longitudinallymoving screw-shaft, the forksecured thereto, the knock-off loosely mounted upon said shaft, andadapted to move longitudinally thereon, the latch for engaging thescrew-shaft, and the knock-off stop moving with said latch,substantially as described, and for the purpose specified.
